This presentation includes forward-looking statements. Actual future conditions (including economic conditions, energy demand, and energy supply) could differ materially due to changes in technology, the development of new supply sources, political events, demographic changes, and other factors discussed herein (and in Item 1 of ExxonMobils latest report on Form 10-K).

8 Goal & Objectives GOAL: Understand how an objects kinetic energy affects the impact it has upon a surface OBJECTIVES: Make and test a durable space suit sample capable of withstanding the impact of a micrometeoroid Work in a team to generate ideas and strategies

10 Rules 1.You have 20 minutes to purchase materials and make your space suit sample 2.Must choose at least four different materials 3.All materials must be purchased in full increments 4.You can not fold materials. They must be cut. 5.All swatches must not be smaller than 10 cm X 10 cm nor larger than 15 cm X 15 cm 6.Your finished swatch should have exactly 14 layers 7.You may enclose up to three sides of the swatch 8.You can not spend more than $120 to complete your swatch 9.Fasteners can not be used to reinforce sample materials

12 Building Your Sample As a team, spend the first 10 minutes reviewing your sample design. You will have 25 minutes to buy your materials and build the sample.

13
13 Testing Your Space Suit Sample 1.As instructed by your camp director, place your sample beneath the impact tester. 2.The camp director will send the center punch through the impact tester one time only. 3.Note the number of layers that were punctured (must make a hole or dent in the sample material to be counted) by the center punch and record your results on the score sheet provided. 4.Calculate your score using the score sheet. The team who earns the most points will be declared the winner!

14 Scoring Calculate your score using the scorecard on back. Keep the following in mind when planning your space suit: 1.Each team will begin with 100 points. 2.For every $3.00 remaining in your bank account at the end, your team will earn 1 additional point. 3.For every layer the center punch punctures, you lose 5 points. 4.Up to 5 points will be added to your teams score if the reason you selected each material is included on your planning sheet. 5.Up to 5 bonus points will be added if the reasons included considered other hazards, extreme temperatures. 6.You will lose 10 points if you do not include a reason why you selected each material. The team with the most points will be declared the winner!

16 Evaluating Your Design Discuss the strengths and weaknesses of your design. How many layers were penetrated by the impact tester? If an astronaut wore your suit on a spacewalk, would he be adequately protected from micrometeoroids? Did your team create a cost-effective suit? Why or Why not?
